Application of cathodic protection on 30 concrete bridges with pre-stressing steel: Remaining service life extended with more than 20 years
conference paper
In view of long term maintenance of its infrastructure facilities the Dutch Highway
Administration (Rijkswaterstaat) has repaired over 1.500 heads of prestressed beams and provided them
with cathodic protection (CP). The heads of these beams showed moderate to severe damage due to rein
forcement corrosion caused by the penetration of chiorides from leakingjoints, which required adequate
intervention on the short term. By means of cathodic protection the corrosion process has been halted,
so that the risk of further degradation of the beams and possible failure of the pre-stressing steel tendons
has been minimized. In addition, the concrete repairs in the chioride contaminated parts of the beams
will be durable.
